Abstract

Denture hygiene is an important factor in the treatment of denture stomatitis. Sterilization of dentures by microwaves has been recommended, but using specialized equipment not available to the average person. This study tests the effect of microwaving on the dimensional stability of dentures (in an unmodified domestic microwave oven). After microwaving (10 mins at 604 W) some measurements showed significant contraction or expansion but reduced exposure (6 mins at 331 W) caused much smaller changes. The dimensional changes are inexplicable but at lower radiation are considered to be harmless.

摘要

义齿卫生是义齿性口炎治疗中的一个重要因素。有人建议用微波对义齿进行消毒，但需要使用普通人没有的专业设备。本研究测试了微波处理对义齿尺寸稳定性的影响（在未经改装的家用微波炉中）。微波处理后（604瓦，10分钟），一些测量显示有明显的收缩或膨胀，但减少照射时间（331瓦，6分钟）引起的变化要小得多。尺寸变化无法解释，但在较低辐射下被认为是无害的。
